Abstract: We review recent developments in Er and Yb based high power fiber frequency combs and introduce their applications in single cycle pulse generation, widely tunable mid and far-IR light sources and frequency conversion to the VUV. We also discuss new methods for precision frequency transfer across multiple octaves demonstrate a relative frequency transfer stability of < 2×10-18 in 1 second.
